NC2152™ series double-wall carbon nanotubes are produced via the Catalytic Chemical Vapor Deposition (CCVD) process. Nanotubes which exit the reactor are then purified to greater than 90% carbon. Then, length is shortened by a post-treatment. Finally the grade is functionalized with -NH2 via a Nanocyl patented process. These products are available in 1 g to 100 g order quantities. A primary interest is in applications requiring surface chemistry characteristics and ease of dispersability.
